BEDFORD — Tragedy shadowed a Bedford anesthesiologist and his young wife who, six weeks ago, were brutally attacked in an apparent home invasion then, this week, were found in a relative's home — the wife dead, the doctor unconscious and a pile of prescription drugs nearby.

The twist of fate suffered by Dr. Eduardo W. Quesada, 52, and his wife, Sonia Quesada, 29, is made more confusing by authorities insistence the two events are separate. Police offered no explanation for how they drew that conclusion.

"It's a separate matter," Bedford Police Chief John J. Bryfonski said Wednesday of the Nov. 24 incident at 7 Proclamation Court that left the couple seriously injured and Monday's events at 49 Kensington Lane.

"The only information that we are releasing is the information that was released in the press release (on Monday)," Bryfonski continued."I'm not going to discuss anything other than what was on the press release," he added.

He noted police "are working the case. The case is open."

According to the statement, one of Dr. Quesada's relatives expressed concern about the couple's welfare Monday morning and Bedford police went to the 49 Kensington Lane condominium where the two had been staying.

Police forced open the door to find Sonia Quesada dead and her husband unconscious. The couple's 2-year-old daughter was staying with relatives at another location.

Dr. Quesada went to Catholic Medical Center, where police said they were able to communicate with him. They would not discuss what he said.Quesada, who is an anesthesiologist and pain management specialist, was in stable condition Tuesday.

An autopsy done on Sonia Quesada's body Tuesday was inconclusive; toxicological test results are pending. The state medical examiner's office said her body showed no signs of violence and her death does not appear to be a homicide.

The condominium is located in The Mews, a private, thickly settled, over-55 community off Meetinghouse Road; the unit is owned by Dr. Quesada's mother, Norma Quesada, 81.

Police found no sign of forced entry, no visible trauma to either spouse and said the couple were the only ones home at the time.

A "large amount" of prescription medication was found in the room, authorities have said.

On Nov. 24, the couple reported an intruder attacked them when they returned to their 7 Proclamation Court home about 10 p.m. The doctor and his wife suffered serious injuries requiring both be hospitalized.

The couple described their attacker as a man at least 6 feet tall wearing a black ski mask and dark clothing.

"It's still a valid description," Bryfonski said Wednesday.

To date, no arrests have been made and the suspect remains at large.

"We're still working the case," the chief said.

Meanwhile, neighbors and workers along Proclamation Court said the $1 million-plus home in which the Quesadas lived now sits empty.

Moving trucks arrived Friday and a few utility crews came and went earlier this week.

Town tax records list Dr. Quesada as the owner of the home; records were current as of Thursday.

Dr. Quesada is listed as a member of Amoskeag Anesthesia PLLC and has privileges at Manchester's Elliot Hospital. Michael O'Sullivan, executive director of Amoskeag Anesthesia at One Elliot Way in Manchester, would not discuss Dr. Quesada Wednesday.

"I'm not really going to answer any questions at this time. Thank you," he said before hanging up the phone.
